During the writer's study on the Mizunami group developed in the environs of Mizunami-Toki-mati, Toki-gun, Gihu-prefecture, he entertained some doubts concerning the fundamental geological conception hitherto been generally accepted by Japanese geologists., In order to solve a part of the doubts, the writer has considered in this paper the following three problems:(1) Significance of fossils as an indicater of "sedimentary environment" of strata, (2) Significance of fossils as an indicater of geological age of strata,(3) Meaning of fossil-facies as one of factors defining lithofacies., These are all interesting and important problems concerning fossil-stratigraphy and biochronology laid in the recent Japanese geologists., The fundamental geological conception hitherto been adopted is standing on a point of view that fossil-stratigraphy is synonymous with biochronology, while in the writer's present opinion these two are to be separated distinctly from each other., Then, the term "biostratigraphy" hitherto generally been used by almost all geologists should be abandoned., It must be done, however, under the world-wide discussion in future., The writer expects that this paper is a reference on the occasion of such a discussion.,
